2, piezo-resistance belongs to disposable use components and parts.After being struck by lightning, the resistance of piezo-resistance can descend and can not restore automatically, it is underground that simultaneously the piezo-resistance of the type does not belong to the standing element and the product technology of various electrical maintenance department, and the user is difficult to repair, reuse, and causes breakdown rate, spoilage all very high.
3, the thunder-strike current by piezo-resistance carries out ground discharge by ground wire, and for guaranteeing safe discharge, ground wire requires to have very little resistance.But ground wire easily increases resistance because of corrosion, and then makes the lightning protection effect variation, and this fault easy-to-search and stay hidden danger not, and the user uses this product not have safety guarantee.
4, existing lightning-protected product power consumption is big, when many users use this series products, easily makes the short circuit simultaneously of electrical network three-phase firewire when thunderbolt, causes the damage of electric power facility.
5, common zero line is successively blown in the short short circuit meeting that causes of natural force, and at this moment, each custom power table Inside coil mutual conduction must make the 220V low voltage electric network become the high-voltage fence of 360V, causes power consumption equipment to damage.And existing all kinds of lightning-protected product all is and connect and to be connected across zero, between the live wire, not have the function of automatic disconnection voltage to cause the damage of power consumption equipment.
